Recently we were trying out the model-driven form designer and noticed the option of adding new input control to the form in it.
Few days back only I wrote about the addition of Subgrid control, however the limitation was that we couldn’t add new subgrid control. But with the new updates, we can now add new subgrid control along with Quick View and other controls also as shown below.
The other option to configure these controls is from the Controls tab of the field properties dialog box.
Hope it helps..
